Noticed that whenever I hit the steeper hills over 2k rpms with 5lbs of boost or more my egts shoot up over 1200, I have to back her off to get them down again and can only cruise at 35-40mph in a 55 zone. I plan on installing an intercooler eventually but am still running down the parts. Anyone running a Water/Methanol setup in their rig thats non-intercooled? Where did you install the sprayer nozzle and what size are you using? What were your egts like pre and post install?

What I do even with an intercooler is drop a gear, rpms get pretty high, but boost is up, egt down, and speed isn't so slow, as far as water meth I've seen that DIY version too and would love to install one as well

i ran a Cooling Mist stage 1 kit on my old OBS with out an intercooler and it worked great.
I found once it came on my EGTs stayed steady and stopped climbing. that was with stage ones and a 5 spd 35s and 4.10s usually pulling about 10000lbs up 5-8 % grades. I ran duel nozzels and used a lot of water though.
